Highway density
WebVehicle Density. Vehicle density can be expressed as. k = n 5280 / l (2) where. k = vehicle density (vehicles per mile) n = no. of vehicles occupying a length l of the road. l = the length of road occupied by the vehicles (ft) (2) expressed in km. k = n 1000 / l (2b) http://www.newgeography.com/content/005552-los-angeles-traffic-likely-to-worsen-with-higher-densities
